Can you add a Command-D shortcut like in Atom / CoderPad / Sublime that selects the current word, then pressing it again selects the next occurrence of the word, and then you can type over n spots with n words selected?

What about to add code completion of user made variables, user created functions (not only have them in the list) and for example completion of class attributes and methods.

For example when user type $t in the class method, it can show $this->var1, $this->var2, or when user have instance instanceName of some class and type for example $inst, then it shows $instanceName->method1()... I think you know what I mean.

And I think it would be great to see parametres and return type of functions as shown in documentation, for example int strncmp(string $str1, string $str2, int $len) above or under the function when I am writing it. Not always, but maybe after pressing some key...?

It would be great if the iOS app had iCloud support as well to link it back to the new mac app, making coding sharing even better.
